Cotton gin



Aug. 28, 1934. J. J. WHITE COTTON GIN Filed Jan. 18, 1932 l n f r Patented Aug. 2s, 1934 veyor 8 in the well known manner.

This invention relates to a cotton gin.

An object of the invention is to provide in a gin, a novel type of mote board arranged in a novel manner relative to the brush.

Another object of the invention is to provide in a cotton gin a mo-te board which is adjustably mounted so that its relation tothe brush may be varied and which is formed of sections adjustable relative to each other, so that the width of the mote board may be varied and the air suction controlled. K

Another object of the invention is to provide in a cottongin a novel type of mote board whereby the metes and heavier particles may be separated from the lint and separately removed from the gin.

With the above and other objects in View the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawing, wherein:

Figure 1` shows a vertical sectional view of the gin showing the mote board therein and showing the flue leading to the condensen Figure 2 shows a longitudinal sectional view of the mote board taken on the line 2-2 of Figure 3, and

Figure 3 shows an underside view thereof.

Referring now more particularly to the drawing, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 designates the gin casing having the hopper-like inlet 2 from above for the inlet of seed cotton. Beneath this inlet there is a transverse saw shaft 3 on which there is fixed a gang of saws as 4 which work between the stripper ribs, 5. The upper ends of these ribs are secured to a transverse cleat 6 across the underside of the top of the casing and the other ends of these ribs terminate at the vertical seed chute 7 at the rear of the gin. At the bottom of this chute 7there is the seed conveyor 8. There are the rotatable feeders 9, 10, the former of which fis locatedrin the lower end of the inlet 2 and the latter of which is located in the casing above the saws and these feeders direct the seed cotton in the direction indicated by the arrows, to the saws. The saws strip the lint from the seed in the usual way and the ribs arrest the seed and direct said seed through the chute 7 to the con- Fixed on the transverse shaft 11 there is the rotatable 'cylindrical brush 12 which rotates in the direc-V tion indicated by the arrow in Figure 1, and

the end cross bars 20,

which cooperates with the saws. top of the casing l there is a separating board 13 which extends transversely across the casing and depends between the saws and the brush.. Leading outwardly from the casing there is the flue 14 through which the lint is conducted to the condenser by means of an air current which is generated by a suitable current generator in the usual manner. The brush 12 sweeps the lint from the saws and carries it into the range of said current whereby the lint is carried on to the condenser. There is a transverse bafe board 15 secured to the inner side of the front wall of the casing above the flue 14 and which extends inwardly to the brush and which is provided to cut off the air current above and to prevent the lint from being drawn around above the brush 12. t

There is a transverse mote board formed of the upper and lower sections 16, 17. These sections extend across the casing from side to side and are preferably formed of sheet metal. The section 16 is preferably reinforced by suitable lengthwise frame members 18, 19, connected by `20 and the intermediate cross bars 21, 21. Secured to the upper ends of the cross bars 21 are the hinges 22, whereby said mote board is hingedly connected tothe underside of the condenser flue 14. The lower or inner margin of the section 17 of the mote board may also be reinforced by transverse bar 23.

The ends of the mote board are located in the tracks 24, 24 formed by the spaced angle irons which are secured to Ythe inner sides of the ends of the gin casing.

Across the upper face of the section 17 of the mote board there is a beveled strip 25 the purpose of which will be hereinafter stated.

As shown in Figure 1 the rnote board is lo` cated beneath the brush and declines inwardly and is spaced from the brush. The lint will pass up over this mote board, but the motes and other heavy particles will drop down by gravity onto the mote board and will drop off into the mote conveyor 26 across the bottom of the gin casing whereby the motes and other foreign objects will be discharged from the gin. The transverse strip 25 is provided to prevent the motes or other foreign objects from passing on up through the condenser flue 14. The tracks 24 may be secured to the ends of the casing by means of suitable bolts as 27 and these tracks may be adjusted to theV proper relation with the brush and then secured to the casing ends. I'he section 17 of the mote Fixed to the Y.

board is adjustable relative to the section 16 so as to give the proper width to the mote board and to control the air current. This may be accomplished by adjusting the section 17 up or down in the tracks 24.

The underside of the upper section 16 has the spaced transverse corrugations 28, 28, thus providing long bearings as 29, 29 in the upper face of the section 16 and rods as 30, 30 are riveted or otherwise secured to the underside of. the' section 17 and these rods Work in said bearings 29 so as to hold the sections 16, 17 closely together and at the same time to permit their adjustment;

If at any time the mote board should be found,

to be not properly spaced from the brush, the bolts 27 may be removed and the tracks 24 together with the mote board adjusted to the proper position and there secured in place.

The drawing and description disclose what is now considered to be a preferred form of the invention by way of illustration only, While the broad principle of the invention will be defined by the appended claim.

What I claim is:

In a cotton gin having an outlet lint ue and a rotatable cylindrical brush adjacent the inlet end of said flue; a sectional mote board across the gin underneath the brush and declining in- Wardly and whose outer margin is hinged to the gin, end tracks for supporting the ends of said mote board, said tracks and mote board being adjustable about the axis of the hinge one section vof said mote board being adjustable along said tracks to; vary the Width of the mote board and a baffle strip across said adjustable section.
